Patented June 2, 1931 UNITED STATES PATENT OFFICE WILLIAM SEIGLE, OFHINTON, OKLAHOMA COIL SPRING METATARSAL ARCH SUPPORT Application filedFebruary 3, 1930. Serial No. 425,669.

tain modifications in the construction of the device in order to applyit to the base; to provide a support which will be new, novel, practicaland of utility; which may be simply and quickly attached within a shoe;which will permit the easy and quick removal of the support from theshoe without the removal of the base; which will be cheap inmanufacture; which will be durable; and which will be eflicient inaccomplishing all the purposes for which it is intended.

With these and other objects in view as will more fully appear, myinvention consists in the construction, novel features, and combinationof parts hereinafter more fully described, pointed out in the claimshereto appended, and illustrated in the accompanying one-sheet drawings,of which,

Figure 1 is a plan view of the device positioned upon a fragment of ashoe sole;

Fig. 2 is an enlarged plan view of the spring attached to a fragment ofthe base; and

Fig. 3 is an elevational sectional view of.

One practical embodiment of the invention as illustrated in the drawingsfollows:

A base 1, having beveled or skived edges 2, and a perforation-3 adjacentits rear central portion. Said base 1 is made of some soft fibrousmaterial such as felt or the like, and

is adapted to be glued or fastened as shown at 4 upon the top surface ofa shoe sole 10 or adjacent a point where the metatarsal arch of a humanfoot normally rests. The entire central portion of said base 1 isslightly depressed as shown at 5 for receiving the largest and lowermostloop 6 of a conical coil spring 7 Said depression 5 is shaped to conformto the shape of said coil 6. Two sides of said loop 6 are connected by aflat metal strip 8, the office of which is pertinent to this applicationonly in that it confines said loop 6 from spreading when any weight isap plied upon the top .coils of said spring 7. Said loop Gterminates ina'free end 9 slightly past the portion of the loop which lies nearestthe .heel of the shoe. Said spring 7 is covered by a cap 11 preferablymade of rubber or other semi-resilient material.

In installing the support in a shoe, the base 1 will be glued orotherwise fastened to the sole at a desired point. The end 9 of saidspring 7 will be inserted through said perforation 3 and the springturned to a position as best shown in Fig. 3. This will force said end 9under the base 1 and on top of the shoe sole 10. The largest coil 6 willsnugly seat in said depression 5 and be held therein by the portion ofloop 6 which is lying be 35 neath base 1. The manner of removing saidspring 7 will be obvious.

Obviously, the invention is susceptible of embodiment in forms otherthan that which is illustrated in the accompanying drawings anddescribed herein, and applicable, for uses and purposes other than asdetailed, and I therefore consider as my own all such modifications andadaptations and other uses of the form of the device herein described asfairly fall within the scope of my invention.

Having thus described my invention, what is claimed and desired tobe'sec'ured by Let ters Patent, is:

1. The combination with a coil spring met atarsal arch support having aconical coil spring for support the metatarsal arch of a human foot of aat fibrous base adapted to be attached to the top surface of a shoesole, said base having skived edges and having a perforation in its rearcentral portion for receiving the free end portion of the lower loop ofsaid spring.

2. Organization as described in claim 1, in which the entire centralportion of the u per surface of said base is depressed to con em to theshape of and snugly fit the lower loop of said sprin 3. The com inationwith a metatarsal arch support having a conical coil spring for supporting the metatarsal arch of a human foot of a lower loo of saidspring having its end portion bent s ightly downward, a fiat fibrous aseadapted to be attached to the top surface of a shoe sole, said basehaving skived edges and having a perforation through its rear centralportion for receiving the bent 'end portion of said spring. 4.Organization as described in claim 3 in which the entire central portionof the u per surface of said base is depressed to con orm to the shapeof and snugly fit the lower loop of said spring.

WILLIAM SEIGLE.
